Beschreibung: Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

Beschreibung: Sauberes und damit sicheres Trinkwasser ist von wesentlicher Bedeutung für die Gesundheit. In den Eingeweiden von Säugern und Vögeln können sich sowohl pathogene als auch harmlose Bakterien befinden. Die Untersuchung von Wasser auf alle möglichen Typen pathogener Bakterien kostet viel Zeit und Geld. Aus diesem Grund wird Wasser auf einen charakteristischen Darmbakterientyp, die Coliforme (einschl. der bekannten <i>E. coli</i>-Bakterien), geprüft. Das Vorhandensein von Coliformen ist ein Hinweis auf eine Kontamination mit Fäkalien. In diesem Experiment testen die Studenten simuliertes kontaminiertes Wasser mit Färbe- und Fluoreszenzreagenzien auf Coliforme. Wasserproben aus der Umwelt können mit denselben Reagenzien geprüft werden. Als Zusatzübung können die gesammelten Proben einem Gram-Färbungs-Test unterzogen werden.

Artikel-Nr: (BE-403)
Lieferant: G-Biosciences
Beschreibung: Biodiversity lab activity is designed for determination of protein contents and biomass in diverse biological samples to study how biomass is related to biodiversity in nature. Students collect and catalogue plant leaf samples from a diverse group of locally available plants. This lab activity involves determination of natural weight of each plant sample, grinding a predetermined amount of each sample, and the subsequent extraction of proteins from the samples. Students then learn to determine protein contents of each plant sample and attempt to relate the protein content with biomass. Students in this lab activity are challenged to think, analyse, and seek answers as to why protein biomasses vary for a given natural weight for different plants. Finally, they will relate that finding to the biodiversity of nature.

Artikel-Nr: (BE-301)
Lieferant: G-Biosciences
Beschreibung: Bacterial conjugation is a naturally occurring process that allows the transfer of DNA from one bacterium to another, which allows the transfer of genetic traits, particularly drug resistance. The kit contains two bacteria with different drug resistance genes and all the tools for students to study bacterial conjugation. This kit teaches the difference between bacterial genomic DNA and the transferable plasmid DNA and the mechanisms of bacterial conjugation. Students will also learn important basic microbiological techniques, including bacterial growth in liquid broth and on solid agar plates, antibiotic selection of bacteria and important aseptic techniques.
VE: 1 * 1 KIT


Artikel-Nr: (BE-314)
Lieferant: G-Biosciences
Beschreibung: A major challenge for molecular biologists and genetic engineers is to easily detect and analyze genetic mutations that occur naturally, causing diseases, or during genetic engineering or cloning, whether deliberate or accidental. Students learn about different types of genetic mutations, including substitutions, deletions and point mutations and about various techniques used to detect genetic mutations. The kit contains all the reagents to screen simulated clinical samples for a mutant gene, using both the polymerase chain reaction (PCR) and restriction digestion mapping. Students conduct a simple clinical diagnostic experiment in order to identify a diseased patient.
VE: 1 * 1 KIT


Artikel-Nr: (BE-502)
Lieferant: G-Biosciences
Beschreibung: Dot blotting is a simple technique to identify a known protein in a biological sample. The ease and simplicity of the technique makes dot blotting an ideal diagnostic tool.
VE: 1 * 1 KIT


Artikel-Nr: (BE-404)
Lieferant: G-Biosciences
Beschreibung: This lab activity is designed to demonstrate the different classes of protein molecules and their classification based on solubility. Students learn fractionation of soluble, insoluble membrane proteins, and cytoskeleton proteins from a tissue sample. The insoluble protein fraction is further fractionated into hydrophilic and hydrophobic membrane proteins. Cell membrane structure and the role of hydrophobic membrane proteins are considered. This lab activity also provides an opportunity to understand characteristics of various classes of detergents and the role of detergents in solubilisation of hydrophobic membrane proteins.

Artikel-Nr: (BE-401)
Lieferant: G-Biosciences
Beschreibung: The Physical Properties of Proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.

Artikel-Nr: (BOSSBS-5276R)
Lieferant: Bioss
Beschreibung: Ca2+/CalmodulinDependent Protein Kinase II (CaM Kinase II) is a multifunctional calcium and calmodulindependent protein kinase that mediates cellular responses to a wide variety of intercellular signals. CaM Kinase II has been shown to regulate diverse cellular functions including synaptic plasticity, neurotransmitter synthesis and release, gene expression, ion channel function, carbohydrate metabolism, cytoskeletal function, and Ca2+homeostasis. Phosphorylation of Thr286 on the kinase produces an autonomously active form of CaM Kinase II. Autophosphorylation of Thr305 inhibits the activity CaM Kinase II. Phosphorylation at this site appears to reduce the association of CaM Kinase II with the PSD and reduce LTP and learning.

Artikel-Nr: (BOSSBS-11719R-CY7)
Lieferant: Bioss
Beschreibung: Calcyon is a single transmembrane protein that interacts with D1 dopamine receptors. Dopamine is a neurotransmitter that regulates synaptic transmission involved in learning and memory. D1 receptors, the most abundant dopamine receptor in the central nervous system, appear to modulate the activity of D2 dopamine receptors, mediate various behavioural responses, and regulate neuron growth and differentiation. Calcyon is present in neuronal cell bodies and processes of the cortex and hippocampus, and it is especially abundant in pyramidal neurons. Interaction of Calcyon with D1 receptors results in a release of intracellular calcium.

Beschreibung: N-methyl-D-aspartate (NMDA) receptors are a class of ionotropic glutamate-gated ion channels. These receptors have been shown to be involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. NMDA receptor channels are heteromers composed of the key receptor subunit NMDAR1 (GRIN1) and 1 or more of the 4 NMDAR2 subunits: NMDAR2A (GRIN2A), NMDAR2B (GRIN2B), NMDAR2C (GRIN2C) and NMDAR2D (GRIN2D). Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008]

Beschreibung: N-methyl-D-aspartate (NMDA) receptors are a class of ionotropic glutamate receptors. NMDA receptor channel has been shown to be involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. NMDA receptor channels are heteromers composed of three different subunits: NR1 (GRIN1), NR2 (GRIN2A, GRIN2B, GRIN2C, or GRIN2D) and NR3 (GRIN3A or GRIN3B). The NR2 subunit acts as the agonist binding site for glutamate. This receptor is the predominant excitatory neurotransmitter receptor in the mammalian brain. [provided by RefSeq, Jul 2008].
